Can the repo indexing task be scheduled?

Hi, since a few months I have a gitea instance installed and running and so far I’m very impressed, so thank you.

In my instance the repo indexer is enabled and has run succesfully.
Now I wondered when this indexing task is run and couldn’t find it in the cron-jobs in admin settings.
I also noticed that the files found in a search are indexed only this one time.

Is there a way to schedule the repo indexing task?
Or is there a way to manually run this task?
